Patent number: 12392934Abstract: An optical device for transmitting/reflecting electromagnetic radiation in a wavelength range of an electromagnetic spectrum. The optical device includes a substrate made of a first material, a coating layer made of a second material that is different from the first material, and a a plurality of cavities formed in surface of the device. The plurality of cavities extend through the coating layer and are partially sunk into the substrate.Type: GrantFiled: October 26, 2020Date of Patent: August 19, 2025Assignees: Hydromecanique et Frottement, Manutech-USD, Université Jean Monnet Saint-Etienne, Centre National de la Recherche ScientifiqueInventors: Thomas Kämpfe, Laurent Dubost, Xxx Sedao

Multilayer optical device with surface texturing and extended cavities for electromagnetic radiation
Patent number: 12287453Abstract: An optical device suitable for transmitting/reflecting electromagnetic radiation in a wavelength range of the electromagnetic spectrum. The device comprises at least a first coating layer made of a first material, a substrate made of a material different from the first material, and surface texturing forming cavities in the device. A lower layer, disposed directly below the first coating layer, is either a second coating layer made of a material different from the first material or the substrate itself. The lower layer has a predetermined thickness. The optical device has cavities that extend through the first coating layer and are sunk into the lower layer through at least part of its thickness. This structure enhances the optical properties of the device for specific applications in electromagnetic radiation transmission or reflection.Type: GrantFiled: October 26, 2020Date of Patent: April 29, 2025Assignees: Hydromecanique et Frottement, Manutech-USD, Université Jean Monnet Saint-Etienne, Centre National de la Recherche Scientifique (CNRS)Inventors: Thomas Kämpfe, Laurent Dubost, Xxx Sedao -
Patent number: 11974569Abstract: The present invention relates to a device for holding human or animal corneal tissue previously removed for photon treatment thereof with electromagnetic radiation, notable in that the holding device comprises: a stack of elements along a longitudinal axis (A-A?) of the device, said stack comprising: a first plate (1) that is transparent to the electromagnetic radiation, a peripheral seal (4) positioned on the first plate (1), the peripheral seal (4) being intended to extend around the corneal tissue (6), a second plate (2) that is transparent to the electromagnetic radiation on the peripheral seal (4), an immobilizing system (51, 52) for immobilizing the stack of elements and able to press the first and second plates (1, 2) firmly against the corneal tissue in order to apply mechanical stress to the anterior and posterior faces of the corneal tissue.Type: GrantFiled: July 17, 2019Date of Patent: May 7, 2024Assignees: UNIVERSITE JEAN MONNET, CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE, CENTRE HOSPITALIER UNIVERSITAIRE, MANUTECH-USDInventors: Philippe Gain, Gilles Thuret, Cyril Mauclair, Clotilde Jumelle, Gregory Egaud
